That was probably written to avoid scaring away non-programmers.
It really should say something like "for non-programmers and programmers who are
not necessarily familiar with Lisp. Really, it's for anyyone interested in Emacs
Lisp.

After `C-h f' (or `C-h v' for variables), you should see a link to the defining
source file near the beginning of the help text. Examples:
eval-defun is an interactive compiled Lisp function in `lisp-mode.el'.
forward-char is an interactive built-in function in `C source code'.
The text `lisp-mode.el' and the text `C source code' are links - click them to
go to the definitions of functions `eval-defun' and `forward-char'. You will not
be able to do the latter if you don't have a copy of the C source code (in
directory `src' under your Emacs installation directory). To see the former, you
will likewise need a copy of the Lisp source code file, in this case
`lisp-mode.el'.
You should always make sure you have a copy of all of the Lisp source code files
for the libraries that you use. It's an invaluable help to consult the source
code. If you have only the byte-compiled files (*.elc instead of *.el), then go
to gnu.org and pick up the source files now.
Yes, you can also use a tags file. For that, you will need to create the tags
file. Consult the doc or Emacs Wiki for more info. Once you have a tags file,
you can easily get to any function etc. definitions. This is an alternative to
using `C-h f' and then following the link to the defining code.
